DISCUSSION
TODAY THROUGH TUESDAY...
SMOKE AND HAZY SKIES LOOK TO BRIEFLY RETURN TODAY AS UPPER LEVEL
FLOW TURNS OUT OF THE WEST BEFORE RIDGING BUILDS IN BY THURSDAY.
CONDITIONS WILL REMAIN DRY AS THE TRANSITION TO RIDGING CUTS OFF
MOISTURE ENTERING THE REGION. HIGHS TODAY WILL BE IN THE MID 80S
TO LOW 90S.
UPPER LEVEL RIDGING REMAINS IN PLACE THURSDAY AND FRIDAY WITH
HIGHS IN THE 90S AND MOSTLY DRY CONDITIONS. BY SATURDAY, MOISTURE
OVER THE REGION BEGINS TO INCREASE AS A DISTURBANCE APPROACHES
FROM THE PACIFIC COAST. A SHORTWAVE AHEAD OF THE MAIN ENERGY WILL
BE ENOUGH FOR SCATTERED SHOWERS AND THUNDERSTORMS (30-60% CHANCE,
HIGHEST OVER THE ABSAROKA/BEARTOOTH MOUNTAINS) SATURDAY.
CURRENTLY, FOR SUNDAY INTO MONDAY, MOST MODELS FAVOR THE
DISTURBANCE SHIFTING NORTHEAST, WITH THE BEST CHANCE FOR
PRECIPITATION CENTERED OVER SOUTHERN CANADA. HOWEVER, THIS WILL
HELP TO FLATTEN THE RIDGE, ALLOWING MOISTURE TO CONTINUE TO ENTER
THE REGION, AND LOW DAILY SHOWER AND THUNDERSTORM CHANCES (10-40%)
TO CONTINUE INTO EARLY NEXT WEEK. HIGHS WILL BE IN THE UPPER 80S
TO LOW 90S THIS WEEKEND INTO EARLY NEXT WEEK. ARCHER
AVIATION
LOOK FOR DECREASING CLOUDS WITH DRY CONDITIONS TODAY. HAZY SKIES
WILL LIKELY RETURN TO THE AREA BY AFTERNOON AS SMOKE FROM DISTANT
WILDFIRES DRIFTS INTO THE REGION FROM THE NORTH/NORTHWEST. SLANT
RANGE VISIBILITY MAY BE REDUCED IN SOME AREAS AFTER 19Z, WITH
SURFACE VISIBILITY REDUCTIONS POSSIBLE AS WELL BY EVENING. BT
